Abstract GUI Into Testable Units

[TheJoeSmo]

Is your feature request related to a problem? Please describe.
None of the GUI is able to have unit tests at the moment. This makes it impossible to tell if the GUI is working by a glance.

Describe the solution you'd like
Abstract every piece into another layer. One layer handles just the dependencies for the GUI and another layer handles the actual logic of the object. This allows us to test the object without testing if the GUI works. This allows for fast testing and no GUI hassle in testing.

Additional context
Future issues should be made for each piece of GUI separately for nicer PRs.
